Domoticz

I have a Neo CoolCam Z-Wave binary doorsensor which I included some months ago. After this I removed the battery, and not used it anymore. However If I look in the hardware, it still shows a "last update" date/time as if it is still operational. Also in the Network topology it still seems to be connected to 4 other nodes. How is that possible?
Should I just interpret the "last update" time stamp as the last time a messages was sent to the device? If so, how can I find "dead"/non-functional devices?

The statistics in the Z-Wave control panel shows - as expected - 1 sent and 1 failed message, however also a recent last-update date.

I know that after a restart of domoticz all my devices have the restart time as "last received"

does that help?

Yes, that helps, this is indeed the time of restart of Domoticz, thanks for the tip!

Still however, If I look at the Groups and Network, it still looks like the sensor is actually still working (which is not). Also in hardware/devices the "the last seen" date/time is correct. However, the battery level is reported as "104%".... Strangly, in the OZW-panel it says "0%".
